An optical link (10) is described for transmitting a microwave signal (30) in modulated optical form over an optical fibre (24). The optical link (10) has a transmitter (12) and a receiver (18). The transmitter (12) splits and converts the microwave signal (30) into two separate optical signals (34 and 36), each of which represent either the positive varying part of the microwave signal (30) or the negative varying part of the microwave signal (30). The receiver (18) combines the two separate optical signals (34 and 36) and converts them back into the microwave signal (30).
La présente invention concerne une liaison optique (10) permettant de transmettre un signal hyperfréquences (30) par une fibre optique (24) sous forme optique modulée. La liaison optique (10) comporte un émetteur (12) et un récepteur (18). L'émetteur divise le signal hyperfréquences (30) en deux signaux optiques distincts (34 et 36) qui représentent chacun, d'une part la partie variable positive du signal (30), d'autre part la partie variable négative de ce même signal (30). Le récepteur (18) combine les deux signaux optiques distincts (34 et 36) et les convertit de nouveau en un signal hyperfréquences (30).
